Steps shown or described. The terms "first", "second", etc. in the specification and claims and the above-mentioned drawings are used to distinguish similar objects, and not necessarily used to describe a specific sequence or sequence.

In the mobile communication system, as shown in FIG. 1, the base station 100 includes a baseband module 110 and a radio frequency unit 120, and the baseband module 110 transmits radio frequency signals to the terminal 200 through the radio frequency unit 120. For example, in the case of explosive growth in data volume, macro stations can only carry less than 30% of the data volume, that is to say, indoor communication systems (such as active indoor sub-systems, passive indoor sub-systems) are the main data volume Carrier. Due to the limitation of its own coverage area, the active room subsystem has to lay out a large number of radio frequency units 120 to meet the communication requirements, and the large-scale layout of radio frequency units 120 will cause huge energy consumption. Therefore, higher requirements are put forward for the energy saving and consumption reduction of the radio frequency unit 120.

Based on the above, the present invention provides a radio frequency unit power control method, electronic equipment and storage medium, which can reduce the energy consumption of the radio frequency unit without affecting the user experience.

It should be noted that the electronic device mentioned in the embodiment of the present invention may be a radio frequency unit 120 or a base station 100 including a baseband module 110 and a radio frequency unit 120. As shown in FIG. 1, the baseband module 110 includes a baseband processing unit 111 and a bridge device 112, the baseband processing unit 111 is connected to the bridge device 112, and the bridge device 112 is connected to the radio frequency unit 120.

In some embodiments, the baseband module 110 only includes the baseband processing unit 111, and the baseband processing unit 111 is directly connected to the radio frequency unit 120.

In some embodiments, the baseband processing unit 111 is a BBU (Building Baseband Unite, indoor baseband processing unit), which is distributed in the indoor sub-system.

It is understandable that in practical applications, as shown in FIG. 2, the baseband processing unit 111 can be connected to multiple bridge devices 112, and each bridge device 112 can also be connected to multiple radio frequency units 120 to implement more terminals 200. Access.

The technical solution of the present invention will be described below in conjunction with specific embodiments.

In the first aspect, as shown in FIG. 3, an embodiment of the present invention provides a radio frequency unit power control method, which is applied to an electronic device. Among them, the electronic device may be a radio frequency unit, or a base station including a baseband module and a radio frequency unit. The method includes:

Step S110: Obtain the utilization status information of the unit channel of the radio frequency unit.

In some embodiments, the utilization status information of the unit channel of the radio frequency unit is proportional to the access amount of the user terminal, that is, the higher the access amount of the user terminal, the greater the utilization status information value of the unit channel of the radio frequency unit.

In some embodiments, step S110 is applied to the base station, the baseband module is used to monitor the user terminal access amount of the radio frequency unit in real time, and the utilization status information of the unit channel of the radio frequency unit is generated according to the user terminal access amount. In other embodiments, step S110 is applied to the radio frequency unit, and the radio frequency unit receives the utilization status information of the unit channel of the radio frequency unit issued by the baseband module.

In some embodiments, the radio frequency unit may be RRU (Remote Radio Unit) or AAU (Active Antenna Unit) or AFU (Antenna Filter Unit), etc., or it may be Other equipment that can realize the function of radio frequency unit. If the method is applied to an active room sub-system or a passive room sub-system, the radio frequency unit may be a miniature radio frequency unit, such as a miniature RRU.

Step S120: Adjust the current switch state of the unit channel to the target switch state according to the utilization state information.

In some embodiments, as described above, the radio frequency unit receives the utilization status information of the unit channel of the radio frequency unit issued by the baseband module, and adjusts the current switch status of the unit channel of the radio frequency unit to the target switch state according to the utilization status information.

Since the utilization status information of the unit channel of the radio frequency unit is generated according to the access amount of the user terminal, the switch status of the unit channel of the radio frequency unit is adjusted according to the utilization status information of the unit channel of the radio frequency unit, so that the unit channel of the radio frequency unit is switched on and off. The state is adaptively adjusted according to the amount of user terminal access, which does not affect the user experience, but also achieves the effect of energy saving and consumption reduction of the radio frequency unit.

It is worth noting here that the switch state of the unit channel of the radio frequency unit includes on or off, and more specifically, refers to the state of the unit channel of the radio frequency unit on or off. In some embodiments, the unit channel of the radio frequency unit is a symbol channel. The symbol channel is the time unit for carrying data and is also the smallest data scheduling unit. It can be understood that selecting the symbol channel as the unit channel to be adjusted has more precise and flexible power control, so that the switching state of the final adjusted target and the utilization state information of the unit channel have a higher matching accuracy.

It can be understood that the unit channel of the radio frequency unit may also be a slot channel or a frame channel. In the communication field, a time period is set when processing data. Assuming a period of 10ms, 10ms is divided into 20 slot channels, that is, slot channel 0～slot channel 19. Each slot channel is divided into 14 symbol channels (for example, OFDM symbols, one symbol channel corresponds to a time domain resource location), that is, symbol channel 0 to symbol channel 13.

In some embodiments, as shown in FIG. 4, step S120 includes the following steps:

Step S121: Turn on or off the power amplifier corresponding to the unit channel according to the utilization state information, so that the current switch state of the unit channel is adjusted to the target switch state.

In some embodiments, the radio frequency unit adjusts the switch state of the unit channel by turning on or off the power amplifier corresponding to the unit channel. It is understandable that the power amplifier refers to the power amplifier, turning on the power amplifier means powering on the power amplifier, and turning off the power amplifier means powering off the power amplifier.

It should be noted that the power amplifier corresponding to the unit channel is turned on and the unit channel is turned on, and the power amplifier corresponding to the unit channel is turned off and the unit channel is turned off.

In some embodiments, as shown in FIG. 5, step S120 includes the following steps:

Step S122: Turn on or turn off the data of the unit channel according to the utilization state information, so that the current switch state of the unit channel is adjusted to the target switch state.

In some embodiments, the data of the unit channel is turned on according to the utilization status information, that is, the unit channel normally transmits data, and the unit channel is turned on at this time. In the same way, the data of the unit channel is closed according to the utilization status information, that is, the unit channel does not transmit data, and the unit channel is closed at this time. By turning on or off the data of the unit channel, the current switch state of the unit channel can be adjusted to the target switch state. In some embodiments, the data of the unit channel is the IQ data (in-phase/quadrature data) carried by the unit channel.

In some embodiments, as shown in FIG. 6, step S120 includes the following steps:

Step S123: Turn on or turn off the data of the unit channel according to the utilization status information;

Step S124: Detect the power of the unit channel;

Step S125: According to the detection result, the power amplifier corresponding to the unit channel is turned on or off, so that the current switch state of the unit channel is adjusted to the target switch state.

In some embodiments, the power of the unit channel is detected based on the data of the unit channel being turned on or off according to the utilization status information. In combination with the above, if the unit channel is a symbol channel, the power of the unit channel is the power of the IQ data (in-phase/quadrature data) carried by the symbol channel. For example, if the IQ data carried by the symbol channel is 30 bits, the in-phase data has m bits, and the quadrature data has n bits, m+n=30, the power per channel is m^2+n^2. The radio frequency unit turns on or off the power amplifier corresponding to the unit channel according to the result of detecting the power. Specifically, if the power m^2+n^2 of the detected unit channel is 0, the power amplifier corresponding to the unit channel is turned off; If the power m^2+n^2 of the unit channel is normal, turn on the power amplifier corresponding to the unit channel to adjust the current switch state of the unit channel to the target switch state.

In combination with the above, adjusting the current switch state of the unit channel to the target switch state can include three implementation methods: (1) Turn on or off the power amplifier corresponding to the unit channel; (2) Turn on or off the data of the unit channel; 3) Turn on or turn off the data of the unit channel, detect the power of the unit channel, and turn the power amplifier corresponding to the unit channel on or off according to the detection result. In practical applications, you can choose according to the situation.

In some embodiments, the status information is used to classify according to levels. When the utilization status information is the Nth level utilization status information, N is a positive integer greater than or equal to 1. Correspondingly, as shown in FIG. 7, step S120 includes:

Step S123: Adjust the current switch state of the unit channel to the target switch state corresponding to the Nth level utilization status information according to the Nth level utilization status information and the preset channel control rules.

In some embodiments, in order to better enable the on-off state of the unit channel of the radio frequency unit to be adaptively adjusted with the amount of user terminal access, multiple levels of utilization status information can be set, and the utilization status information of each level corresponds to a different The amount of user terminal access, that is, as the amount of user terminal access gradually decreases, some unit channels can be gradually closed in a stepped manner, which is flexible and energy-saving without affecting user experience. When the utilization status information is the Nth level utilization status information, the radio frequency unit adjusts the current switch state of the unit channel of the radio frequency unit to correspond to the Nth level utilization status information according to the Nth level utilization status information and preset channel control rules The switch state of the target.

In some embodiments, the preset channel control rules include:

The Nth level uses the mapping relationship between state information and the target's switch state.

In some embodiments, the utilization status information is divided according to levels, and the utilization status information of each level maps a target switch state. It is worth noting here that the switching state of the target refers to which unit channels of the radio frequency unit are turned on and which unit channels are turned off, or several unit channels are turned on and several unit channels are turned off.

The utilization status information is divided into four levels (including the first level utilization status information, the second level utilization status information, the third level utilization status information and the fourth level utilization status information). The unit channel is the symbol channel, and there are 14 symbols in total. Take the channel as an example, and give an illustrative explanation:

The on/off state of the target mapped by the first-level utilization state information is the symbol channel fully open, and then all the symbol channels are opened according to the first-level utilization state information;

The second level uses the state information to map the target switch state. The first case is state A (2 symbol channels are off and 12 symbol channels are on). Then, according to the second level, the current switch state of the symbol channel is used. The status is adjusted to 2 symbol channels off and 12 symbol channels on. The symbol channels can be randomly selected to be turned on or off, as long as the 2 symbol channels are turned off and the 12 symbol channels are turned on. It can be understood that, in some examples, if the symbol channels are currently 5 off and 9 on, then 3 of the 5 off symbol channels are directly selected to be turned on at random to improve work efficiency. The second case is state B (symbol channel 0, symbol channel 1 is off, symbol channel 2～symbol channel 13 are on), then the current switch state of the symbol channel is adjusted to symbol channel 0, according to the second level of state information. Symbol channel 1 is turned off, and symbol channel 2～symbol channel 13 are turned on;

The switch state of the target mapped by the third level using state information is the same as the second level using state information;

The switch state of the target mapped by the fourth level utilization state information is that the symbol channel is fully closed, and then all the symbol channels are turned off according to the fourth level utilization state information.
